The setup in the bathroom in my flat is somewhere in between these two scenarios. It's difficult to find an angle that captures the bathroom in its entirety, but here's a picture to give you an idea:
I was talking to my flatmate about the setup, and he agreed that it was pretty cool, in a way... I said: "Hey, you can take a shower while sitting on the John! That's gotta be handy if you're ever in a rush in the morning, or really hungover..." Doug said: "Well, yeah, I was really tired this morning, actually, so I gave it a try! All I need to do is add in shaving as well, and I'll be doing all three things at once!"
There you go: dreams can come true in this city.
